# rpa-dmn-operation

This repo contains the sources for a DMN activity for the RPA tool UiPath.

For creating and evaluating the DMN decisions, an instance of [Camundas open-source engine](https://camunda.com/download/) is required.

## Installation

1. Go to the [releases](https://github.com/bptlab/rpa-dmn-operation/releases) section, and download the `*.nupkg` file from the _assets_.

1. Copy the package to the [UiPath directory for local packages](https://docs.uipath.com/studio/docs/managing-activities-packages#adding-custom-feeds).

1. In your UiPath project, [install the package](https://docs.uipath.com/studio/docs/managing-activities-packages#installing-packages). (_All packages_ → _local_, you can also search for `DMN`)

1. Now, the new DMN activity should be available for use as any other UiPath activity. You can find it by the name `External Decision Service`.

## Usage

After adding a DMN acivity to your workflow, the following elements need to be configured in the _Properties_-Panel:

**Inputs**:

- **Input Variables**: the list of variables in UiPath that should be passed to the decision service

- **Input Variables Names**: the list of input names of the decision table in the same logical order as the input variables.

**Options**:

- **Decision Key**: The identifier of the decision to evaluate. This ID can be found in the Camunda engine after deploying the decision table.

- **Service Host**: The URL under which the Camunda engine is reachable.

**Output**:

- **Decision Result**: The name of the UiPath variable, the decision result(s) should be stored in.

> Example: The decision table requires the inputs _Type of Shipment_ and _Destination_. In the RPA bot, those values are stored in the variables _shipmentType_ and _destination_. To provide the correct mapping of UiPath variables and inputs of the decision table the following must be configured:

> 

> Input Variables = `{shipmentType, destination}`

> 

> Input Variables Names = `{"Type of Shipment", "destination"}`

> 

> By this, the DMN activity knows how to map the variables to the decision table inputs.

>

> The decision key looks something like `"Decision_1hyvppg"` and the service host, if the engine is deployed locally, might be `"http://localhost:8080"`.

> :information_source: Please bear in mind that this activity is currently in the prototype stage.
